ABSTRACT:
A combined sheet compressor and transfer device for attachment to spaced prongs of a file folder fastener including a plate-like cross member for receiving the prongs of the file folder fastener and bearing against a stack of sheets to thereby act as a compressor, a pair of substantially parallel flexible elongated legs of substantially rectangular cross section extending from the plate-like cross member, and flexible tubular members at the outer ends of the legs of a slightly smaller internal diameter than the width of the prongs so as to be distorted at their outer ends when mounted on the prongs to thus provide a relatively smooth junction therewith at their outer ends to facilitate the transfer of sheets from the prongs onto the legs when functioning as a transfer device, diametrically opposed reinforcement bosses on opposite sides of the tubular members for overlying the edges of the prongs to thereby prevent the edges of the prongs from cutting the tubular members, and a tapered portion between the junctions of the legs and the tubular members for providing a smooth transition therebetween to facilitate the transfer of sheets from the legs onto the prongs.
